GC250 Technical Manual 41
Bit 10. If this bit is “ON”, the controller checks that the GCB is closed, to activate
possible warnings/locks configured with the preceding bits.
Bit 11. If
this bit is “ON”, the controller activates a fault only if the fuel valve is activated.
Bit 13. If this bit is “ON”, to activate any warning/lock configured with the preceding
bits, the controller checks the status of any digital input configured with the function
“2705 - Disable the protections on the ANALOGUE measures”. The warnings/locks
will be activated if no digital input is configured as such, or if they are all OFF.
Bit 14. If this bit is “ON”, the fault entails the arrest of the fuel pump
You can set any combination of these bit.

All odd functions AIF.XXXX require the use of program BoardPrg3 for the definition or the
upload of the sensor characteristic curve (see par. 5.7.3In fact, every digital input can have
an AND/OR logic associated, which determines its status.
Functions AIF.1000, AIF.1100, AIF.1110, AIF.1200, AIF.1200, AIF.1210, AIF.1220 use pre-
set conversion curves suitable for the VDO most common sensors instead.
